Function
Antitoxin component of a potential type II toxin-antitoxin (TA) system. Acts as an antitoxin against host toxins RnlA and LsoA, preventing them from degrading T4 bacteriophage-derived mRNA and thus permitting successful virus infection. Stabilizes middle (8-10 minutes) and late (18 to 28 minutes) T4 gene transcripts.
